greenhouse gases emissions have increased during the last century due to human activities such as agricultural practices, fossil fuel burning and industrial practices. the formation of greenhouse gases, in particular n2o or co2 is strongly controlled by both soil temperature and soil humidity. laboratory experiment was conducted to assess the response of grassland and arable soils with regard t...

abstract- as the world's population has grown and become more urban and affluent, waste production has raised drastically. wastewater reuse has been identified as a way to alleviate water scarcity and improve crop productivity and environmental sustainability. to address the issue, a soil column experiment was carried out in a 3 × 3 factorial randomized block design including three treatments o...

The aim of the study was to compare the effects of stress (contamination trials) on the microorganisms in zinc-polluted soil (5,018 mg Zn kg(-1) soil dry weight) and unpolluted soil (141 mg Zn kg(-1) soil dw), measured as soil respiration rate. In the laboratory, soils were subjected to copper contamination (0, 500, 1,500 and 4,500 mg kg(-1) soil dw), and then a bactericide (oxytetracycline) co...

BACKGROUND The aim of this study was to determine response patterns and mechanisms of soil respiration to precipitation increases in subtropical regions. METHODOLOGY/PRINCIPAL FINDINGS Field plots in three typical forests [i.e. pine forest (PF), broadleaf forest (BF), and pine and broadleaf mixed forest (MF)] in subtropical China were exposed under either Double Precipitation (DP) treatment o...

Measurements have been made of 222Rn release from diverse soils in the region surrounding Málaga, Spain. These flux measurements were carried out by two methods. A direct method using a static chamber technique and another indirect method obtained from concentration profile measurements of 222Rn in the soil air. The effects of meteorological variables and other parameters on 222Rn flux were stu...

In this study, to investigate the effects of runoff harvesting on soil properties in the semiarid forest, runoff harvesting through semi-circular bund was considered as a method to conserve soil and thereby combat tree mortality. In order to evaluate this hypothesis, runoff was harvested through the semi-circular bund affecting soil quality and moisture storage. The selected forest site is loca...
